Document Summary

4) multi-store model continued short-term store (sts) You transfer info you paid attention to from the sensory store into the sts. Knowledge in the lts allows for active, top-down processing of info in sts. 5) sts (wm) capacity memory span is limited. Consistent limitations across a range of stimuli and experimental paradigms: Perfect recall is difficult for lengths more than 3 or 4 items. Span for numerals, letters, words is 7 +/- 2. 6) impact of magical 7 +/- 2 bonus. Sts/wm capacity is a cognitive constraint that impacts all systems. Emphasis on re-coding and chunking paved the way for info processing. Why not just have one box called memory instead of. 3 kinds of evidence for separate stores: Serial position curves in free recall tasks. Spoiler alert: stm and ltm are separate, but they are used together when we try to remember. A list of words will be read to you, giving you 2 seconds to study each word.
